Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed June 3, 1910. Serial No. 564,848.

To all whom it may concern:

Be it known that I, LLOYD DOUGLAS, a citizen of the United States,residing at Los Gatos, in the county of Santa Clara and State ofCalifornia, have invented new and useful Improvements in Bracket-Seats,of which the following is a specification.

This invention relates to a bracket seat for the use of carpenters,painters, shinglers, and other mechanics in working upon shingled roofs,the object of the invention being to provide a device of this characterwhich will form a firm and secure seat support and which. after use, maybe folded in compact form for storage and transportation.

The invention consists of the features of construction, combination andarrangement of devices, hereinafter fully described and claimed,reference being had to the accompanying drawing, in which Figure 1 is aside elevation of the device as mounted for use upon a roof. Fig. 2 is arear elevation of the same. Fig. 3 is a bottom plan view of the deviceas unfolded for use, and showing in dotted lines the supporting elementsarranged in folded position. Fig. a is a side elevation of the device asfolded for storage and transportation.

The device comprises a platform com posed of a central section 1 andrelative front and rear sections 2 and 3 united by hinges 4 so as topermit said sections 2 and 3 to swing to a position at right angles tothe section 1 and parallel to each other, whereby the device may befolded in close compass for storage or transportation, as shown in Fig.4. A latch 5 is pivoted to the free longitudinal edge of the section 3and has a hook end to engage a headed pin or stud 6 011 the freelongitudinal edge of the section 2, by which the parts may be fastenedin folded condition.

Upper supporting bars 7 are pivoted, as at 8, at different distancesfrom their for ward ends to the under side of the section 2, so thatsaid bars may be swung to an inoperative position substantially inparallel relation longitudinally of said section, or swung to extendfrom front to rear across the under sides of all three sections, 1, 2and 3 to form supports to prevent collapse of said sections when theplatform is in use.

The rear ends of the bars are adapted when disposed in supportingposition to be engaged with hooked spring latches 9 on the platformsection 3, said latches having beveled free ends to permit the bars toslide into and out of engagement therewith. The forward ends of the bars7 have bifurcated portions 10 to receive the upper or forward ends oflower supporting bars 11 which are adapted to assume an inclinedposition and rest upon the surface of the roof and are provided at theirupper and lower ends with holding spurs 12 and 13. Each bar 11 is formedat its lower end with a longitudinal series of transverse openings 14.

The rear ends of the bars 7 are formed with eyes 15 to which arepivotally connected the upper ends of legs 16 adapted to dependvertically from the rear of the platform when the device is set up foruse. The relatively lower ends of these legs are forked, as at 17 tostraddle the rear ends of the bars 11 and are transversely perforatedfor the passage of securing bolts 18 provided with winged clamping nuts19. Loosely pivoted to a bracket plate 20 on the section 3 are braces 21adapted to extend outwardly and downwardly in divergent relation andhaving angularly bent apertured lower ends 22 adapted to engage thebolts 18, by which the legs and braces may be coupled to the lowersupporting bars to stay and reinforce the same from the upperlongitudinal bars and the rear platform section.

Figs. 1 and 2 show the device as set up for use, from which it will beseen that the platform is supported in an open and horizontal positionto provide a firm seat support for the workman, and that the bars 11rest upon the surface of the roof and are firmly secured thereto by thespurs 12 and 13. The supporting elements in this arrangement have arigid relationship so that the bracket as a whole in operative positionmay be detached from any one portion of the roof and shifted to anotherportion as occasion requires.

When it is desired to fold the device for transportation, the legs 16and braces 21 are disconnected from the bolts and the bars 7 withdrawnfrom engagement with the latches 9, whereupon the parts may be folded tothe dotted line position shown in Fig. 3, allowing the platform to becollapsed in the manner shown in Fig. 4:, thus disposing the device inconvenient form for carriage or storage. The advantages of the device inthis particular will be readily understood, and it will be apparent thatthe invention provides a simple, convenient and stable support for theuse of mechanics of all kinds when working upon shingled roofs. Bypassing the bolts 18 through the openings 14: at different points alongthe length of the bars 11 the platform may be supported at differentangles of inclination to the horizontal, as occasion may demand inperforming different kinds of work.

Having described my invention, I claim 1. A device of the characterdescribed comprising a foldable platform, upper sup porting bars pivotedat one end to said platform to swing to a position longitudinally ortransversely thereof, latches carried by the platform for engagement bythe free ends of the bars to secure them in a transversely arrangedposition, lower supporting bars pivoted at their upper ends'to theforward pivoted ends of the upper supporting bars and having spurs attheir upper and lower ends, coupling legs pivoted to the free ends ofthe upper supporting bars, braces pivoted at one end of the platform,and means for detachably connecting the free ends ofthe lower supportingbars, legs and braces.

2. A device of the character described comprising a foldable platform,upper supporting bars pivoted at one end to said platform to swing to aposition longitudinally or transversely thereof, latches carried by theplatform for engagement by the free ends of the bars to secure them 1n atransversely arranged position, lower supporting bars pivoted at theirupper ends to the forward pivoted ends of the upper supporting bars andhaving spurs at their' upper and lower ends, coupling legs pivoted tothe free ends of the upper supporting bars, braces pivoted at one end tothe platform, and means for detachably connecting the free ends of thelegs and braces with the free ends of the lower supporting bars atdiifer ent points along the length of the latter.

3. A device of the character described comprising a foldable platformcomposed of central and front and rear hinged sections, upper supportingbars pivoted at one end to the front section, latches carried by therear section for securing the free ends of said bars thereto, lowersupporting bars pivoted at their upper ends to the pivoted ends of theupper supporting bars and having spurs at the opposite ends thereof,coupling legs pivoted to the free ends of the upper supporting bars,braces pivoted at one end to the rear platform section, and means foradjustably connecting the free ends of the legs and braces with the freeends of said lower supporting bars.

In testimony whereof I aflix my signature in presence of two witnesses.

LLOYD DOUGLAS.
